Rhododendrons and horse muck !

We inherited about a dozen, mature rhododendrons/azaleas when we bought our house. They are in a shady area under trees and a very overgrown beech hedge. We have severely pruned the beech hedge now and the rhododendrons are now getting more light and seem to be doing a lot better this year. I have a huge amount of well-rotted horse manure (with and without straw) - any reason not to mulch the rhododendron with it ??

What do you mean by compost it ?? I just have mine delivered by a friend who dumps a tractor/trailer load in our field. I leave it to sit there for at least 6 months before using it (far too much to shift it anywhere near my compost bins One heap is with straw, the other is just pure poo

LOL The field is only 3/4 acre - next to our house. I have the greenhouse and raised beds on it, plus fruit trees. There's a gate onto the road so our friend just drives his tractor in and dumps We've spent 5 years renovating the house, so only just getting the garden (jungle) sorted

One of my pot grown Rhodos. It normally flowers in March/April, but this year didn't flower till May. It's about 30yrs old, bought in the days when I didn't make a note of the varieties, so if anyone can ident it there's a Twix for you!
